just use FOIL (First, Outer, Inner, Last).

( √2 - √3 ) X ( √2 - √3 )

First: √2 X √2 = 2
Outer: √2 X -√3 = -√6
Inner: -√3 X √2 = -√6
Last: -√3 X -√3 = 3

and then add them together.

2 - √6 - √6 + 3
5 - 2(√6)

The answer is 5 - 2(√6) .

An initial deposit of $7,000 earns 6.5% interest, compounded monthly. How
zavuch27 [327]

Answer:

$34,300

Step-by-step explanation:

First, we need to find how much interest is earned in one month : 7,000 * 6.5% = 455

455 is how much you gain monthly, multiply that by 12 to find the annual interest so 455 * 12 = 5,460

You then multiply that number by 5 to find the interest of the span of the 5 years

5,460 * 5 = 27,300

You add the original number to the interest with 27,300 + 7,000 = 34,300 in the account

SOMEONE HELP ME PLEASE

Answer:

<h3>Angle 6 = 101°</h3><h3>Angle 5 = 79°</h3><h3>Angle 7 = 79</h3>

Step-by-step explanation:

Angle 6 will 101°

This is because we can see that Angle 4 is alternate interior angle to Angle 6 and alternate interior angles are always equal.

<h2>So angle 6 will be 101°</h2>

Angle 7 = 79°

Here we can see that Angle 6 and angle 7 are supplementary which means it has a measure of 180°

So the value of Angle 7 will be

180 - 101 = 79

<h2>Hence the measure of angle 7 will be 79°</h2>

Angle 5 = 79°

Angle 7 and Angle 5 is vertically opposite to each other and we know that vertically opposite angles are always equal so the measure will be 79°

<h3>Hence the measure of Angle 5 will be 79°</h3>

(NOT A MULTIPLE CHOICE)
Vsevolod [243]

Answer:

  a, b, c --- all <em>not</em> representative

Step-by-step explanation:

The question posed by the engineer is "are residents of the city in favor of ...".

The only representative sample is one from a pool that includes <em>all residents of the city</em>—not just those who (a) use the road, (b) live along the road, or (c)  own homes.

__

<em>Additional comment</em>

The engineer may want to refine the question. As posed, it would include children, homeless, and/or institutionalized residents of the city as well as drivers and tax-payers. In inclusive cultural traditions, "residents of the city" may also include animals, plants, water, air, and other holders of spiritual energy.

So we multiply 13 by 3 to get the answer!

13:39

or 39 feet!
